WARNING Potential risks can be drastically reduced by wearing the Personal Protective Equipment listed in this chapter. These protections are indispensable. Always operate with due care around dangerous areas marked by the appropriate warning signs on the equipment.

2.6 General warnings DANGER The UPS works with dangerous voltages. Only SKILLED TECHNICIANS must perform the installation and ordinary maintenance operations. No part of the UPS can be repaired by the operator. Extraordinary maintenance operations must be carried out by LEGRAND Technical Support Service personnel. DANGER Before beginning any installation and/or maintenance operation, make sure that all the DC and AC power sources are disconnected. The UPS must be installed with an earth connection to avoid high leakage currents. First connect the earthing cable. Check during each installation and/or maintenance operation the continuity of the earthing system. DANGER The UPS is powered by its own DC energy source (batteries). The output terminals may have a dangerous voltage even if the UPS is not connected to the AC power network. The DC power source could comprise multiple battery drawers in parallel and/or external battery units. Disconnect all battery drawers and external battery units before performing any installation and/or maintenance operation. WARNING A battery can present a risk of electrical shock and high short circuit current. The following precautions should be observed when working on batteries: a) remove watches, rings or other metal objects; b) use tools with insulated handles; c) wear rubber gloves and boots; d) do not lay tools or metal parts on top of batteries; e) disconnect the charging source prior to connecting or disconnecting battery terminals; f ) determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock can be reduced if such grounds are removed during installation and maintenance (applicable to equipment and remote battery supplies not having a grounded supply circuit). Do not dispose of batteries in a fire. The batteries may explode. Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. The batteries installed inside the cabinet must be disposed of correctly. For the disposal requirements refer to local laws and relevant standards. CAUTION The UPS functions with TT and TN systems. It has a pass-through neutral architecture: the status of the output neutral is the same as the input neutral. When a load needs a different neutral status from the input status, it is necessary to place downstream of the UPS a suitably scaled isolation transformer protected in compliance with the standards in force. For electromedical applications which require the medical IT system, it is necessary to have an insulation board downstream the UPS that ensures compliance with the regulations in force for this type of application.

5. Installation All the electrical connection operations are carried out on the connection terminal strips inside the UPS. For the Trimod HE 10, 15, 20, 30 TT models, it is necessary to unscrew the distribution drawer locking screws and pull it outward to get at the distribution terminal strip. For the Trimod HE 30 TM, 40 and 60 models, it is necessary to remove both the lower panels to get at the terminal distribution strip. Outside the drawer there are the fuse breakers (depending on the model), the output switch, the mains input switch and the manual maintenance bypass switch. In the case of Trimod HE 30 TT, the fuse holders have been installed inside the terminal strip.

5.2.2 Preliminary operations Before connecting the UPS, check that: • the mains input voltage and frequency correspond with the values indicated in the technical data on the UPS rating plate; • the earthing has been carried out in compliance with IEC (International Electrotechnical Commission) standards or local regulations; • the electrical system has been fitted with the necessary differential and thermal-magnetic protections upstream of the UPS input.

5.2.3 Wiring For all the models it is possible to pass the cables from the bottom into the opening in the base. It is also possible to pass the cables through the metal plate with holes fixed on the rear panel through 4 screws. In this case it is essential to block the cables by means of appropriate cable glands, not supplied, to be inserted into the holes in the plates. The plates have four holes with a diameter of 33 mm and one hole with a diameter of 16 mm.

5.2.4 Earthing

Before carrying out any other installation operation, connect the earthing wiring coming from the low voltage switchgear to the earthing terminal on the UPS terminal strip.

5.2.5 Protective devices To ensure proper protection from overloads or output short-circuits, it is necessary to use adequate protection at the electrical system level. Install automatic residual-current and thermal-magnetic breakers upstream of the UPS on the input line, selected according to the indications in the tables shown in chapter 11.

5.2.6 Backfeed protection

The Trimod HE UPS is fitted with an auxiliary contact for the actuation of the external backfeed protection (protection against power transfer towards the input). This auxiliary contact has been created with a C/NC/NO relay and is available on the the relative tripolar “BACKFEED PROTECTION” terminal on the terminal strip.

22



If the UPS detects a voltage backfeed, the relay is energised and changes status, enabling the disconnection of the input lines that must be done externally as indicated in the diagrams shown below. The relay contacts characteristics are : • Maximum applicable voltage: 250Vac. • Maximum applicable current: 5A, cosφ = 1 INDICATION If, during operation, the UPS signals that the backfeed protection has been actuated, contact the LEGRAND Technical Support Service.

It is then possible to move onto the insertion of the power modules and battery drawers into the UPS (depending on the model) and in the external modular battery units (if there are any). WARNING The Trimod HE UPSs have electrical distribution sized for the nominal power of the equipment and must be used exclusively with the power modules provided as shown in the “Mechanical characteristics” table in chapter 11 of this manual. Do not use power modules that differ from those indicated and do not exchange the modules with each other and/or replace them to vary the power of the UPS. The model, the nominal power and the type of power module to be installed in the Trimod HE UPS are indicated in the manuals and on the rating plate inside the door of the UPS. The type and the nominal power of the power module are indicated on a rating plate at the back of the module. Insert the power modules one at a time checking that they abut. Fix them to the frame with the two screws provided with each module. Use SHC M4x20 screws (hex socket head). The two fixing screws also act as the module's earth connection and must both be fixed for safety purposes. If one or more power modules are not installed, the free slots must be covered by installing in each of them the plastic mask of the kit 3 108 66. The mask must be fixed with two SHC M4x20 screws. Insert the battery drawers one at a time checking that they abut. For each drawer, tighten all the fixing screws provided. Use SHC M4x20 screws (hex socket head). In the case of the Trimod HE 30 TT do not insert abutted the drawers and do not screw them up. If one or more battery drawers are not installed, the free slots must be covered by installing in each of them the plastic mask of the kit 3 108 65. The mask must be fixed with two SHC M4x20 screws. 36



6. Configuration and Start-up DANGER All the configurations and start-up operations may only be done by a SKILLED TECHNICIAN (paragraph 2.2.1)

6.1 Introduction This chapter contains all the information necessary for a correct configuration of the Trimod HE UPS and for its subsequent startup. The factory configuration provides for THREE PHASE INPUT and 120° THREE PHASE OUTPUT.

6.2 Input configuration The Trimod HE UPS automatically recognises the input voltage, frequency and number of phases if the electrical connection on the terminal strip is modified. CAUTION Make sure the neutral wire is always connected.

6.3 Output configuration The Trimod HE UPS does not automatically recognise the electrical configuration on the output terminal strip. For this reason it is always necessary to select the type of output voltage from the control panel according to the applied load. The default configuration for the Trimod HE UPS is 120° three phase 400 Vac. The UPS can also be configured to obtain a unique single output phase 230 Vac in the 10 kVA, 15 kVA, 20 kVA and 30 kVA TM models. If the UPS is configured with three phase output, it is possible to select the management of the three phase as follows : - THREE PHASES 120°: this is the default setup and is usually used if three phase loads are applied on the UPS output (e.g. three phase electrical motors) or if there are both three phase and single phase loads powered by the UPS. In this case the UPS manages the three output phases protecting the three phase load. For example, if an excessive load is applied to one of the three output lines, the automatic bypass switches all three output lines. - THREE SINGLE PHASE OUTPUTS: this setup is necessary if three single phase lines have been created with the common neutral on the UPS output. In this case, the UPS manages the three outputs completely independently of each other. For example, if an excessive load is applied to one of the three output lines, the bypass intervenes only on the overloaded line while the power supply continues to be guaranteed on the other two by the UPS. If the input is single phase, the three lines are not in phase but rather with a phase shift of 120° and therefore cannot be connected in parallel. If the input is three phase, the outputs are in phase and the possibility of using the bypass is guaranteed. For the correct selection of the output configuration, follow the instructions given in paragraph 6.5.

6.4 Pre-start-up checks Before powering the equipment, carry out the following checks: 1. Check that the mains input switch S3 of the UPS is open (OFF position). 2. Check that the battery fuse breakers of the UPS FB+ and FB- (if the model includes them) and those inside the Trimod HE BATTERY (if present) are open (OFF position). In the case of Trimod HE 30TT in which the fuse breakers are installed in the terminal strip, check that all the battery drawers are not installed abutting and thus the string of batteries is interrupted. 3. Check that the maintenance bypass switch S1 and the output switch S2 of the UPS are open (OFF position) 4. Check that the wiring on input and output has been done and that all the connections have been tightened up properly. 5. Check the correct phase sequence of the input line. 6. Check that the parameters (voltage and frequency) of the input line are compatible with those shown on the UPS rating plate. 7. Check that all the power modules are inserted properly and that the fixing screws of the power modules are present and screwed up to abut the relative slots (use SHC M4x20 screws with hex socket head ) 8. Check that all the battery drawers, if present, are inserted properly and that the fixing screws of the power modules are present and all the fixing screws are screwed up to abut (use SHC M4x20 screws with hex socket head ) In the case of the Trimod HE 30 TT, push the battery drawers one at a time to abut and screw them up with the fixing screws.

6. Follow the path UPS Setup  Output  Voltage and UPS Setup  Output  Frequency to check that the output voltage and output frequency are the ones required. 7. Follow the path UPS Setup  Batteries  Total KB to select the correct number of KB (Battery Kits) installed. INDICATION 1 KB (Battery Kit) represents a string of 20 batteries in series. In case of models with internal battery drawers and external modular battery units, 1 KB comprises 4 battery drawers.

It is necessary to install 1 KB every 10 kVA of nominal UPS power in case of modular units with battery drawers. For example, for the Trimod HE 40 it is necessary to have at least one external modular battery unit with 4 KB (16 battery drawers). In case of non-modular 94h external battery units, each unit represents 1 KB and 1 KB is sufficient for all the Trimod HE models. 8. Follow the path UPS Setup Batteries Capacity to select the correct value of the capacity in Ah of the individual KB. INDICATION The UPS calculates the total battery capacity as produced by the total KB * Capacity. 9. Leave the Service Mode pressing the ON/OFF key. 10.

CAUTION Do not remove the power modules during the functioning of the UPS without first having activate the proper replacement procedure (described in paragraph 7.4). The removal of one or more power modules without the proper use of the replacement procedure could damage the equipment. CAUTION The keys for opening the UPS door must not be left at the operator's disposal. WARNING The installation and maintenance manual and the quickstart sheet must not be left at the disposal of the operator.

6.6 ECO MODE setup The UPS Trimod HE has a functioning mode called "eco mode", in which the load is supplied directly from the mains through the automatic bypass circuit inside the power modules. If the output voltage leaves the window of tolerance (-20% / +15% of the set output voltage), the UPS actuates its inverter stage and supplies the load with the energy stored in the batteries. When the input lines is back within the tolerance values, the UPS is automatically taken back to the eco mode. It is possible to change the functioning mode between on-line and eco mode (and vice versa) both with UPS on and with the UPS off (through the Service mode). To activate the eco mode, enter the main menu and follow the path UPS Setup  Bypass  Off-line Mode. Select "Enabled" and press the ENTER key to confirm the choice.

Power module replacement or inclusion of new modules 1. Check that the procedure for setting the maintenance bypass mode described in the paragraph above has been applied. 2. Extract the power module after undoing the two fixing screws. CAUTION On the cover of the power module there are two holes from which it is possible to see two leds that signal the presence of dangerous voltage on the rear connector . Before performing any operation on the power module, make sure that these leds are off. If they are on, wait for them to turn off. 3. Check that the two leds visible through the two holes in the side cover of the new power module are off. If they are on, wait for them to turn off. 4. Insert the new power module in the same slot where the previous one was located. 5. Fix the new power module to the UPS frame with the two screws provided along with the power module, making sure they abut. Use SHC M4x20 screws (hex socket head). The two fixing screws allow the power module’s earthing and must both be fixed for safety purposes. The procedure described does not need further manual setups from the control panel. The UPS automatically recognises the new power module and it is configured automatically. INDICATION The procedure for adding power modules is the same as the previous one. In step 2, remove the plastic masks of the kit 3 108 66 that cover the empty slots where you want to add new power modules. Exiting from maintenance manual bypass To transfer the UPS from the maintenance bypass status to the online status, do the following: 1. Check that the output switch (S2) is open (OFF position). 2. Close the battery breakers of the UPS and of all the Trimod HE BATTERY (if present). 3. Close the mains input switch (S3) bringing it to the ON position. 4. Press the ON/OFF key to start up the UPS. When the display shows the text “ to confirm UPS turn ON”, press the ENTER key.

Keep the ON/OFF key pressed for at least two seconds. 2. When the display shows the text “Turn off the UPS?”, press the ENTER key. 3. Wait for the shut down operation to complete. 4. Open the output disconnector switch (S2) bringing it to the OFF position. 5. Open the mains input switch (S3) bringing it to the OFF position. 6. Open the battery breakers of the UPS and of all the Trimod HE BATTERY (if present). 7. Press the ON/OFF key to discharge any internal capacity. 8. Open the breaker upstream of the UPS that supplies power from the mains. Once these operations have been carried out, the UPS is without voltage. It is possible to proceed with the maintenance operations. WARNING Inside the upper part of the UPS unit where the command boards and the contact interface card are located there could be dangerous voltage due to the connection of the external backfeed control line. Be careful of connector EC9 of the contact interface card to which the backfeed line is connected.

EC9

Note: by making the external backfeed protection as per the diagram in paragraph 5.2, it is possible to isolate the line from the outside and make it safe.

7.5 Battery drawers requirements The battery drawers of the UPS and modular Trimod HE BATTERY can be installed/replaced in two different ways in addition to the one with the UPS off described in paragraph 7.4.2. DANGER A battery can present a risk of electrical shock and high short circuit current. The following precautions should be observed when working on batteries: a) remove watches, rings or other metal objects. b) use tools with insulated handles. c) wear rubber gloves and boots. d) do not lay tools or metal parts on top of batteries. e) disconnect the charging source prior to connecting or disconnecting battery terminals. f ) determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock can be reduced if such grounds are removed during installation and maintenance (applicable to equipment and remote battery supplies not having a grounded supply circuit).

44



INDICATION The battery drawers must always be added/removed in multiples of 4 (1 KB consists of four battery drawers for models with internal battery or external modular battery units). If a KB is added, start from the free slots at the bottom and covered with the plastic covers of the kit 3 108 65. If a KB is completely removed, cover the free slots with the empty battery slot covers of the kit 3 108 65. If the installation/removal procedure changes the total number of KB installed in the UPS, it is necessary to update this setting from the control panel. After concluding the installation/replacement operations, calibrate the batteries through the control panel to get precise indications regarding the total autonomy of the UPS. To perform this operation, enter the main menu and follow the path Tools  Batteries  Batt. Calibration. Press the ENTER key to confirm the choice. INDICATION Always replace only 1 KB at a time

7.5.1 Installation/replacement of battery drawers with UPS on-line If the UPS has more than 1 KB every 10kVA of power supplied on the output, it is possible to replace 4 battery drawers (1 KB) a time with the UPS functioning on-line. This operation can be carried out on models with internal batteries and on modular Trimod HE BATTERY. The replacement procedure is the following: 1. Check that the UPS has installed more than 1KB every 10kVA of power supplied. 2. Check that the UPS is not functioning in battery mode and that the battery charger is in the “maintenance” or “standby” state. To check the status of the battery charger, go into the menu UPS Status  Measures  Batteries and check the fourth item shown on the screen. 3. Extract the four battery drawers relative to just one KB. To add another KB, do not remove any battery drawer. 4. Insert the four new battery drawers and fix them with the screws provided with them. 5. Repeat steps 2, 3 and 4 for every KB to install/replace. INDICATION If the UPS switches to battery mode during the operation, do not extract nor insert battery drawers. It is possible to resume the operation when the UPS returns to the on-line mode. If during the operation the input mains power fails, the autonomy is reduced: it is therefore necessary to carefully assess this circumstance in relation to the application before beginning the procedure.

7.5.2 Installation/replacement of battery drawers with UPS in maintenance manual bypass This procedure is valid for both models with internal batteries and for modular Trimod HE BATTERY. 1. Check that the procedure for placing in maintenance bypass mode described in paragraph 7.4.1 has been applied. 2. Extract the four battery drawers relative to just one KB. To add another KB, do not remove any battery drawer. 3. Insert the four new battery drawers and fix them with the screws provided with them. 4. Repeat steps 2 and 3 for every KB to install/replace. 5. To leave the manual maintenance status actuate the procedure described in paragraph 7.4.1. CAUTION During maintenance bypass operations, the load is not protected because it is supplied from the bypass input line.

7.6 Extraordinary maintenance Contact the LEGRAND Technical Support Service if there are failures that require the access to internal parts of the UPS.
